Arduino Voice Recognition Module V3

DescriptionVoice Recognition Module is a compact and easy-control speaking recognition board.This product is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as command. Users need to train the module first before let it recognizing any voice command.This board has 2 controlling ways: Serial Port (full function), General Input Pins (part of function). General Output Pins on the board could generate several kinds of waves while corresponding voice command was recognized.What are the updated features ?We already have Voice Recognition module V2 and it supports 15 commands in all and only 5 commands at the same time.On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could to be imported into Recognizer. It means only 5 voice commands are effective at the same time.On V3, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into recognizer. It means 7 commands are effective at the same time.

Parameter1、Voltage: 4.5-5.5V2、Current: <40mA3、Digital Interface: 5V TTL level for UART interface and GPIO4、Analog Interface: 3.5mm mono-channel microphone connector
and microphone pin interface5、Size: 31mm x 50mm6、Recognition accuracy: 99% (under ideal environment)Feature1、Support maximum 80 voice commands, with each voice 1500ms
(one or two words speaking)2、Maximum 7 voice commands effective at same time3、Arduino library is supplied4、Easy Control: UART/GPIO5、User-control General Pin Output

ExampleHere i will show you an example how to control RGB by voice.1. Recording We need to send serial command to this module. You may need a USB-TTL module to connect it with PC. Send command 0xaa11 to record. Please refer to the manual for more information.Please notice that :Please record the following voice instrctions in order send command 0xAA21 to import group 1.2. Hardware connectionTXD of Voice recognition Module should connect with RXD of USB-TTL module or Arduino .
RXD of Voice recognition Module should connect with TXD of USB-TTL module or Arduino .3. Code

int redPin = 11; // R petal on RGB LED module connected to digital pin 11
int greenPin = 9; // G petal on RGB LED module connected to digital pin 9
int bluePin = 10; // B petal on RGB LED module connected to digital pin 10
byte com = 0; //reply from voice recognition

void setup()
{
Serial.begin(9600);
pinMode(ledPin, OUTPUT); // sets the ledPin to be an output
pinMode(redPin, OUTPUT); // sets the redPin to be an output
pinMode(greenPin, OUTPUT); // sets the greenPin to be an output
pinMode(bluePin, OUTPUT); // sets the bluePin to be an output
delay(2000);
Serial.write(0xAA);
Serial.write(0x37);
delay(1000);
Serial.write(0xAA);
Serial.write(0x21);
}

void loop() // run over and over again
{

while(Serial.available())
{
com = Serial.read();
switch(com)
{
case 0x11:
color(255,255,255); // turn RGB LED on -- white
break;

case 0x12:
color(255, 0, 0); // turn the RGB LED red
break;

case 0x13:
color(0,255, 0); // turn the RGB LED green
break;

case 0x14:
color(0, 0, 255); // turn the RGB LED blue
break;

case 0x15:
color(0,0,0); // turn the RGB LED off
break;

}
}

}

void color (unsigned char red, unsigned char green, unsigned char blue) // the color generating function
{
analogWrite(redPin, red*102/255);
analogWrite(bluePin, blue*173/255);
analogWrite(greenPin, green*173/255);
}

Upload the code above to Arduino. Please disconnect TX and RX while uploading code because uploading would occupy serial interface.4. Result ShowAfter uploading is done, connect RX and TX, and then press RESET button on Arduino.You can see the video on Youtube

Example 2Here we will show you how to use the GPIO output to control other device.Step 1First you have to record the voice instruction. Send command 0xAA12 (group 2).Please record the following 5 voice instructions in given note you have to speak clearly.Step 2Connect the device with LEDs in the following way :

Step 3Import voice group 2 by command 0xAA22 or set pin GCH HIGH and pin GCL LOWSpeak voice instruction.Now you could control the LEDs by voice. Product list
